SUPPORTING DEVICE Filed April 14, 1936 2 Sheets-Sheet 2 ATTORNEY 4 Patented June 15, 1937 UNITED STATES PATENT OFFICE SUPPORTING DEVICE George T. Mott, Pearl River, N. Y. Application April 14, 1936, Serial No. 74,259 10 Claims. (01. 155-58) This invention relates to. supporting dynamic mechanism, suspended from and in relation to: a fixed, stationary framework, said mechanism; providing for a glide oscillating action, freely floating, and untrammeled within its operating throw limits, and with an included, self-contained, gravity return power phase, in association with a suspended, oscillating cradle element, so designed: as to carry a load, and whereby said cradle operates in the horizontal, or in close approximation thereto, and i in greater length of travel, than the actual length of the suspended supporting levers, and wherein said oscillating action may be performed thru resilient, tentering contacts whereby; the initially required power demand shall at the point of application be reduced to a comparative minimum, and the developed internal dynamic stresses shall be equalized, whereby; the action is in smooth continuity, and free from terminal shock and chatter, while continuing in operation under the influence of power conservation, and is thereby especially adaptable to domestic swings, porch and de-luxe gliders and other personal usage devices and the industrial arts as adjustable thereto.

An object of the invention is to provide therein, an action similar to that, of a freely swung element, as when suspended from an upper structure, such as a common fulcrum but where in this application, the customary triangular plot of said swing element, is truncated, but at angular relationship to the horizontal and at any predetermined point, and the upper structure above said truncated line is thereafter eliminated.

An important object of the invention is to provide within said action, a throw length in the cradle-support, materially in excess of the actual length of the suspended, supporting means.

An additional functional object of applicants mechanism, is to provide in a supporting device of alternate concave and convex supporting surfaces, such action as to free the device, while freely floating from the customary distressing, inertia terminal shock, incident to a swing action, as in known, gliders and other suspended devices, and as evident at the conclusion of each swing oscillation, and to substitute therefore, a resilient, vibrant, tentering freely floating terminal action of such mechanical delicacy, as to be imperceptible in relation to shock effect.

A further object is to so poise the load weight in angular relation to the horizontal, as to predetermine the load lift, and the consequent initial power demand, and the subsequent gravity effect in relation. to the measures of power conservation, while retaining a smooth, vibrant, tentering action, with a terminal advance in repose, beyond the customary center of gravity as evidenced by a, vertical position of the supporting levers.

Further and of major importance, is the o b-- ject contained in the means employed for power conservation, (generally muscular) thru the inclusion of variables in the leverage relations of the several elements employed, and of variable means in connection with alternate concave and convex contact surfaces, whereby, said muscular effort in its power application and in comparison with theknown art is relatively at a very low power tension and provides means to eliminate fatigue.

A prime subject of importance, is indicated in the means included to preserve a dynamic equilibrium within the developed power stresses and further thereby preserve thru the same measures the mechanical integrity thereof.

A further and basic object, is included in the mechanism, wherein are provided measures of resilience against the customary terminal shock effect, and to absorb the recoil in power conversion against the inertia incident to a change of direction and without chattering effect.

A most important object of the invention is in the application of said floating-glide mechanism to say: a so-called porch glider, a garden type or childs swing, to a floating de-luxe comfort or rest chair, or similar devices operated by muscular effort, generally pedal, wherein is the assured, comparative minimum power effect desired thru the inclusion of the power conservation measures, as amplified hereinafter.

A desirable object is further included in the mechanism for any predetermined adjustment inthe throw or in power tension and which makes possible the maintenance of the throw in the horizontal orin close approximation thereto and thereby the application of the floating-glide principle to a comfort or rest device or to gymnastic purposes, and likewise the incorporation into service for automobile and train seats, and it is this possible variable relationship of constituent parts which also provides for the adjustment level and pitch of an individual seat element, and which makes the mechanism also adaptable to industrial purposes.

In the accompanying drawings, which are referred to herein, and form part hereof, are several illustrations, setting forth certain principles of the invention, and therein are shown, several embodiments of the invention as applied to gliding-floating, supporting devices.

Of the drawings:

Fig. 1 is a front elevation of the device in its simplest form-employing but a single unit of the invention and as applied, in this instance to a childs swing.

Fig. 2 is a side elevation in detail of Fig. 1.

Fig. 3 is a top view in plan, of Fig. 1, showing the basic supporting member for this type.

Fig. 4 is diagrammatic, showing the means of plotting the mathematics, and the dynamics thereof.

Fig. 5 shows an end elevation of Fig. 1, in part, showing in line, a supporting element, but as applied to so-called porch type gliders, with a low swing head, and showing also, an alternate means of cradle support in substitution for a normal two unit end, but where a second unit is shown in association and in phantom.

Fig. 6 is a plan view of Fig. 1, showing one end with its load-supporting surfaces and supporting structure.

Fig. '7 is a complete view in perspective, of a four unit device, in accord with the principles outlined, and as applied to single or multiple seat units, is shown in the preferred form.

Fig. 8 is a sectional elevation on the line 8-8 of Fig. 5, showing in side elevation the construction of a single floating member mounted on its suspension frame and including the companion integrity element.

Fig. 9 is a sectional elevation on the line 9-9 of Fig. 5, showing a floating unit in full line with an additional unit of a floating member in phantom but with an auxiliary load supporting device, employed specifically, when but one floating lever is desired.

Parts of Fig. 9 are broken away.

Fig. 10 shows alternate means for effecting the variable leverage relationship, with its resultant power conservation for effecting the minimum required power application in the floating-glide action.

Fig. 11 is another means of effecting power conservation by varying the lengths in the respective lever parts and thus varying the leverage differential, and this is especially adaptable when an extremely low power demand is desirable, and is a preferential means when applied to comfort and domestic, low tension devices, as operated by muscular effort.

Referring now to the drawings in detail and first to Figs. 1, 2, 3 wherein is illustrated a gliding-floating oscillating device in accordance with the principles contained herein, said device operating in this instance, as a cradle, a swing, or a glide support, and wherein said cradle is maintained in the horizontal or in close approxima tion thereto.

In the figures noted, the objects of the invention as previously outlined are fully contained, and as applied say, to a childs swing.

In a swing of the current art, the suspending element describes an arc incident to its pendulum throw, and dependent on an obligatory height, thereby raising the occupant a variable distance above the horizontal and because of this height, demanding a comparatively heavy power application and also endangering life and limb in the event of a fall therefrom, said pendulum action also causes many persons to become distressingly ill.

In the instant invention, the swing action is in glide effect and while not restricted as to its length of plotted throw, constantly maintains the horizontal as related to the floor level or remains in close approximation to said horizontal,

Referring to the drawings in detail, and again to Figs. 1, 2, 3, wherein is shown means comprising a frame member suitable to a load supporting device, and sustaining a supporting member 6, from which member the operating unit is suspended thru the load supporting surfaces 8-9 and their contact bolts 'I-la.

Said operating unit, Figs. 1, 2, 3, consists of load supporting surfaces 8-9 including alternate concave and convex surfaces in preferably continuous convolutions, said supporting surfaces 8-9, and further set in combination in angular relation to the horizontal, and including a load carrying leverage device 20, with arm members H-l2 projecting from said lever and contacting said surfaces 8-9 and arranged to oscillate thereon.

The device is shown to effect the same swing action, as that of an element suspended from an elevated fulcrum, but that thru the angular relation of the combined surfaces 8-9, and in relation the horizontal, there is effected a truncating of the triangle of pendulum swing, but in said angular position, and the load travels in the horizontal or in close approximation thereto, while power conservation is effected in the provision for limiting the load lift thru angular relation.

It is by reason of the angular relation of the load supporting elements 8-9 and by further reason of the truncating of the triangle of pendulum swing, that; the center of gravity of the load in repose, does not conform to the initial vertical center line of the upper structure, when said line is drawn thru the intersection of the conforming lines of the lever 28 as projected from the extreme throw limits of said lever 29. and it is in the predetermined diiferential in angular load supporting means 3-9, or the pitch thereof, which provides for the relative ease of operation and the conservation in power application, and the regulation for any desired degree of power application.

It is in the continuation of said load supports 8-9 into the concave formation shown, toward the extremities of throw of said lever 29 wherein resides the property of resilience against the customary terminal shock.

It is in the continuation of the load supports 8-9 into the concave terminal formation and at thejunction of said concave formation with the convex formation wherein resides the vibrant, tentering action at the said point of con tact shown by the number 8 of Fig. 2, and where said tentering action, at the verge of either direction, absorbs the inertia effect, and assists in combination with the variable relations in the load carrying lever 29, to effect power conservation, said power conservation consisting of a reduction in the power required to operate said device when compared with the art.

At the conclusion of each said terminal throw as shown in the diagram Fig. i, there is also effected by reason of the said upturned concave faces of the contact element 8-9 and the angular relationship to the horizontal of the said element 8-9 an automatic impulse in the return throw action and without the immediate application of power.

Whenthe instant initial action in the. return,

of the load'cradle-has been accomplished thru the. mediums of the said continuing concave formation of the. supporting. elements 8-9, and

further to said *load supporting members 89.

being. poised inangular relation to the horizontal,.. but little additional power is required to continue. the throw in either direction, as the reaction has been absorbed in applied power, and this also assists in power conservation.

The concave and convex surfaces of the load carrying means 8-!) are preferably, as shown, in continuous association to restrict .thedevice to. compact dimensions.

It has been found, that; where the load supporting. means 8-9, Fig. 2 are in alternate, concave and convex formation, there appear at the junctions of said concave and convex formation, tentative flat spots, which temporarily impedes the smooth and continuous operation of the device, as for instance; when the roller Ida of .Fig. 2, is in load carrying-contact at the identical point; where the roller Ma is shown in Fig. 2, on the suppOTting member 9, and the roller l3a correspondingly at the low throw point on the member 8. When the last phase of power conservation is desired the lever Fig. 11 can be used to advantage.

In the inclusion of Fig. 11, the short arm IE1), is set facing the power throw, or at the lower end of the hypothetical inclined line Fig. 2, on which line the load supports 8-9 are poised.

When substituting the lever of Fig. 11 for the lever 20, in Fig. 2, and when the contact pulley Ma is in the identical position shown in said Fig. 2, then the substituted lever a, in association with said inclined line of support will be in a forward position. much in advance of that shown initially in Fig. 2, and a most desirable position from which to apply the initial backward impulse, with its power conservation, and of great importance, when it is especially desirable that the impulse power be very low. In a high swing element, however, this power may be incidental, but in a comfort device, becomes imperative in its lowest power application.

Again when the lever, Fig. 11, has been substituted for the lever 20, of Fig. 2, it is found thatin the relative shortening of the arm I2, Fig. 2, by the substitution of the arm l2b of Fig. 11, and in conjunction with the suspended lever 20, and the inclined relationship of the contacts 8-9, there is included a load-power leverage differential when-the power is applied at the ,pointof load support, and which reduces thereby the measure of initial power demand thru an, effective load lifting capacity which may equal in emciency that of a pinch bar, thereby effecting the desired minimum in power demand and with included measures for an easy, smooth, shockless gravity return, as applied to them-- clined supporting means.

When Fig. 11, with said variables in the relative length of the arms Illa-12b or equivalent variables in the diameters of the roller contact members, is incorporated in Fig. 2 in substitution for the lever 2! the leverage relationship is highly accentuated, and the means for load power conservation thusevidenced in the impelling muscular effort.

In the embodiment of the drawings is furtherv shown the means relating to the retained mechanical integrity of the device.

When the load carrying leverQlLand its associat con act emb V 3 I 411 r z u pr e upon,

the load carrying members 8-9, thereisamarkecl. tendency when the power is suddenly or unequallyapplied to: derange the entire mechanism.

To obviate any such possibility of derange ment, a companion power integrity member 26-26 is employed, said integrity member being also suspended from the basic support 6, Fig. 3 by bolted. means l5--I5a, wherein, said members preserve not only the mechanical integrity but primarily maintain the internal power stresses in: constant equilibrium.

The element -426, suspended from a fixed, stationary. supporting member, 6, is shown in plotted, companion association with the load sup porting element 8-9, said load supporting element 3-9, shown in concave and convex formation, whereon the contact elements i le-l 5, of the load carrying lever 20 oscillates.

The said companion element 26.placed in remote relation to the said load sup-porting element 8-9, is associated in peculiar, related conformation, and in further connection with a given contact point 25a, and wherein said point 25a, is remotely located on the said freely swung load supporting lever 20, said point oscillating in close contact with the said element 2li26.

The contact points l4-|5 and 25a, are formed in equi-angular relation on the freely suspended, load carrying means, wherein said points l4-!5-25a are retained, within hypothetical circular contact relation, and ride rotatively on said hypothetical circle, moving also in oscillation. on the said load supporting elements 8.9, whereby the initial stresses, incident to imposed power application, are maintained in dynamic equilibrium, as when the power is spontaneously applied against the remote point of load impingement 2!, and by muscular effect, and in such tension as may be determined by personal mood.

Said equi-angular relationship in the contact point M--l525a, provides further for the retained augmented throw in the lever 25, wherein the load carrying cradle 25, suspended on said load carrying lever 20 is carried in horizontal throw, or in close approximation thereto, in greater distance than the actual length of said load carrying lever 20.

The aforesaid load supporting members 8- 9, arise outwardly and in alternate concave and convex formation and from a common concave section thereof, (contact point 13 Fig. 2), develops thereafter, in continuation into convex surfaces. in each direction, said load supporting members being further transformed into additional, continuing terminal surfaces in each instance, and said terminal surfaces set concave to the angular line on which said supporting load surfaces are poised in their divergent relationship and their further combined relation, to the horizontal, thereby contining said supporting surfaces 8-9 alternately concave and convex in their angular determination.

It is in these concave continuations at the terminal of said load supporting members 8-4), wherein is contained the resilience against the terminal shock effect in the movement of the lever 20 and it is further in the relationship at the continuing contact points, where the terminal concave surface 8-$i, is joined by the preceding convex surface thereof, that: the contact member (as Hla Fig. 2) and as mounted with said alternate concave and convex load supporting surfaces, is poised in tentering relationship there-, to,- whereby the customary recoil is absorbed in, said ,tenterina. effect, and, applied against. the .re..

means for shock elimination.

When a forwardly inclined load carrying lever, with lateral arms and contact members thereon is receding from its forward position of repose, under an applied power, it has been found, that upon reaching the vertical and thereafter; there is a continued lessening in the leverage power application, and to preserve intact the measures of included power conservation, it is seen in the instant invention, that; when the said load carrying lever 20, has reached the vertical, the contact point Ma of said lever, will be in contact at the peak of the forward convex section of the load supporting element 8-9, and by reason of the close balance in the load-leverage relationship, tentering thereon, riding thereby backwardly under the continued application of power and entering thereby upon the more precipitate, centrally disposed, concave section of the said load carrying element 8-9, whereby; the leverage effect in relation to the implied load is comparatively increased, and the actual power required to continue the throw to a position approximating the terminal thereof, is but slightly augmented and in a lesser ratio, than is shown for the length of throw preceding the advent into the said centrally disposed concave section of said load supporting element 8-Q, thus retaining the feature of power conservation.

In Figs. 1, 2, 3 is shown it, a typical swing seat.

The diagram Fig. 4, is described substantially in the same manner as Figs. 1, 2, 3.

The respective load carrying members lib-91) are shown mounted in angular relation to each other, and with the contact faces on the inside of the angle within the intersecting lines which enclose the angle formed by the terminal throw lines of the lever Ella. wherefrom they diverge, said supporting elements Bb-Sb in combination, are also set in oblique, angular relation to the horizontal, which horizontal is represented by the basic support line 6, Fig. 1.

The aforesaid integrity members 26-26 are also and independently adjustable to the oblique angularity of the combined supporting elements 8-9 and in companion relation thereto, assur ing the continued integrity of the structure under any circumstances. See Fig. 2.

The mechanical action and the dynamics of the device are indicated in Fig. 4, wherein the load supporting elements 8b5b, with their alternate concave and convex surfaces are shown, and set in mean angular relationship to the horizontal.

In Fig. 4, is shown further the resilience of the device, and wherein there are also included the concave continuing terminals of said supporting elements 8b9b, and it is by reason of said included concave terminals, and the included associate elements therewith, wherein. is provided a resilience against the customary terminal shock effect, and whereby the impetus in the recoil is absorbed in applied power against the inertia of the return throw.

Further; it is in the immediate relationship of said continuing, concave and convex formations of said supporting element lb-9b, and in coordination with the load carrying leverage device 20 and its associate arms Ila-Ra that: at any given moment of efiective operation the peak load contact, incident to the direction of operation,

always corresponds with and is imposed upon, a curved peak of said load supporting surface 8b9b and in tentering contact therewith, and is in position at all times to function instantaneously, relatively free from excess load impingement under the influence of gravity, and when operating in either direction, whereby the conservation of applied power is effected.

It has been found that within the imposed degree of angularity of said load supporting elements 811-91), resides the control of the power tension adjustment, which permits of operation, between that of comparatively negligible conserved power demand, when applied to comfort floating devices, and that of relatively heavy power demand for gymnasium, or industrial service, and it is in said means of adjustable, angular relationship to said horizontal, wherein lies the power differential and the incident velocity of the cradle device in its gravity return to a normal forward position of repose.

When the combinations of circumstances are such, with the included load supporting means db-9b, Fig. 4, in oblique angular relationship to the horizontal 6, and in such degree as to induce the ease of operation effective in power conservation, or a low power application, and when the lever 20, Fig, 2 has completed its throw to the extreme left, and that in consequence thereof, the supported load is at its extreme backward throw, and the supporting pulley |3a, Fig. 2, of the lever arm H, is in the immediate point of contact application with the number 3 of Fig. 2, and said point 8 being the point of junction between the concave and convex bearing surfaces 8-43, Fig. 2, and when the lever Fig. 2, begins its return throw to the right, it is found there is instituted a momentary, vibrant tentering action, at the said contact point 8 of Fig. 2, which tentering action operating in either direction absorbs all inertia and tendency to shock effect and prevents chattering.

In Fig. 4, is further shown the means for increasing, at the point of load contact 2|, the throw-length of the lever 20a, beyond that of the actual length of the said suspending lever 20a, said suspending lever 20a, Fig. 4, with its load shown in contact at 2|, when moving in either direction, right or left, floats upon the load supports |3-9, set as aforesaid in angular relation to the horizontal, so that in the action of said lever 20a, and the cross-head Ill thereof, and thru the roller contacts l3a and Ma on said supporting contacts 8-9 shown in Fig. 2, the movement generally is an average movement parallel in effect to the inclined line, on which said supporting means 8-9 are graphically mounted, and on which said load supporting elements 8-9 are poised, thereby extending the throw-length of the lever 20, at its included cradle load contact point 2|, thru the augmented range of throw, included within the tentative length on the load supports 8-9, Fig. 2, and incident to the initial length of the included lever 20, and the leverage relationship within said lever and the arms ||b-|2b thereof, and whereof the load supporting end of the lever 20 continues in horizontal throw fully or in part thereof.

In the variation of the load supporting elements 8--9, from the horizontal, it is important, that the load levels ZDA-ZDA, be unequal in length, in the (tentative) same degree that the hypothetical line of the said load supports 8-9 initially varies from the horizontal, in which variation of length is an additional measure to -prise .the said load supporting elements, and

preserve a throw within. limits in the horizontal and a maintained throw in close approximation to the horizontal.

Inasmuch 'as all operating measures are dependent onlyonthe load supporting elements 89, the respective lengths in'the lever Zlla, exerts no influencewhatsoever on the gravity effect or other measures excepting only the relation of the cradle to the "horizontal.

Fig. 5 illustrates another means of effecting the floating-glide principle of this application, and .'.is actuallyamodification of Fig. '7, inasmuch as parts are omitted and'other parts substituted therefor, to effect a more economic structure. The description 'of this device in principleis substantially the same as that of the preceding figures.

In Fig. 5. a substantial frame WOlk'x'fid is provided, on which frame work are'moimted, the load supporting members 8d'9a, thru the adjustable contact bolts 'l'la, said load supporting members 8a'-9a, :being alternatelyl of 'con cave and convex formation, with continuing terminals ii8b9b of concave formations said terminal forming the means of resilience inthe oscillations of the load contact elements l3a-l4a on said load supporting members 8a-9a.

In further association with said load supporting elements 8a9a, is the companion element 26, also in. adjustable relationship to the said supporting element"8a-9a, and in further combination with the contact elements I 3a-l4a- 25a, and in conjunctionwith thesuspended load carrying lever 20a, and the cradle means Zla.

In this device of'Fig.-"5, the duplicate lever 20a, as seen in Fig. 7, and shown in phantom in Fig. 5, is omitted, as is also the associate load supporting means 8a9a, and the duplicate companion element 26, and'substituted for the said omitted measures, is. a companion element 2%, plotted as before in association with supporting means 8a-9a, but from the contact point 21, said point 21, being atthe end' of the cradle 2| a, at which point saidduplicate lever is omitted, said companion element 26b,'being in adjustable relation to the framework and t0 the horizontal or its plotted'deviationtherefrom.

Imposed upon the load carrying lever 20a,

and at the load'point? 2!, is,-as previously'noted,

one end of the cradle 2 la, and in pivotal relation to the load 'carrying'leven-Mla, the opposite end of said cradle 2m, is imposed upon and travels freely, on the companion element ilfih'thru the contact element 27a, the impelling power being supplied as before by muscular effort.

It will be seen, thatithe'function of horizontal throw in main or in partmay be observed in this device, and in connecti'on'with afree and untrammelecl floating measure, and with the further measures of freedom "from shock,rand the means of resilience, as well as the ease of operation and the inherent power of gravity return throw.

A modification of theinvention is shown in T Fig. 7, wherein is illustrated a supporting device, used in gliders as adapted to so-called porch types and further adaptable to service for extreme comfort in-operation, and for highly refined surroundings.

In this modification, there is shown a suitable framework 5a, and imposed thereon'are the load. supporting members-8a-9ayda-9a,

each shown in alternate concave and convex formation, and in continuation and with concave terminals 8b9b, and which in combination comare imposed onsaid frame work 5a, thru the boltedrmeans l, said bolted means being capable of any reasonable'adjustment. It is in the concave terminals of the said load supporting elements 8-9 wherein the resilience in the contact, with the rolleror pulley contact elements l3--l4 occurs, and it isvin the immediate point of juncture, between the concave terminal continuations and :the adjacent convex surface of said load supporting element, wherein occurs the tentering contact with the contact points I3-l4 and where-further the implied load thereon tenters on the verge of either direction and under the influence of gravity, that is when the cradle in Fig. 7, isat the moment of reverse from the-position shown, Fig. 7, and with the power momentarily applied against the load carrying end of thelever 20a, the load will be found to tenter at the said point of peak juncture shown at M of power conservation.

Freely suspended on said load supporting elements 85J, are the load carrying levers 20w, slidably engaged in oscillating with said load supporting elements thru the contact rollers or pulleys l3l4, of the arms ll-I2, whereby the load carrying end of said lever 20a, oscillates in parallel throw,-while the contact elements l3-l4 of said lever 20a thru the cross-head l0 and the extending arms lI-I2 thereof, oscillate in the general direction of the parallel, but more in reference to the hypotheticalangular line on which said load supporting elements 8-9 are poised, which angular line of load poise, determines the power phases in operation, and preserves the smooth even floating-glide effect as well as predetermining the velocity thereof.

At the point of applied load 2|, is shown a journal or bearing, and engaging within same, fitted shaft ends shown at 2 2] of Fig. 7, which shafts carry the immediate cradle structure 3536 in oscillation.

Adjustably mounted and arranged to conform to the said load supporting element and in any variable relation, are the elements 26, said companion means26 also suspended from said frameworklia.

From any given point on the load carrying lever 20a, is an included contact point, with its contact pulley 25.

It is from said contact point 25, in connection with the contact points l3--l4, and when oscillating on the load supporting elements 8-9, wherein the curved relationship of the companion members 26-26 is plotted.

As aforesaid the substitution of the lever 20a of Fig. 11 for the lever 213m of Fig. 7, accentuates theleverage differential and increases the ease of operation; thru power conservation.

IirFig. 6, is shown a framework member on which the supporting device is suspended, showin gspecifically one end of Fig. 7, and in plan view, wherein 5a. is the means on which the element is actually impinged, thru the load supporting elements 8a"9a., lib-91), shown in staggered relation to condense the unit in compact form, and supporting respectively thereon, the

contact elements l3l4, of the lever 20a, in their oscillating relation to the supporting element a, suspended thereon, and in conjunction therewith, a companion element 26, and in further association the auxiliary companion means 261).

In Fig. 9, is shown, an end elevation on the line 9-9 of Fig. 5, parts broken away and parts in phantom said parts in phantom being those omitted in Fig. 5, and wherein is shown in full lines, one of the supporting measures 8a-9a,, as shown in staggered relation in Fig. 6, and. where in are illustrated the said load supporting meas- .ures tor-9a, with the adjustable bolted means "id, and the contact means M, of the lever 20a, the companion means 26, and the Contact means therewith 25, of the said lever 20a.

In Fig. 11 is shown the variable leverage rela tionship, wherein, when the short arm I21), of the lever 26a, is turned forward, or in the direction of and against the applied muscular power at the point of load support 2|, the leverage differential will tend to exert an increase in the relative power relation at the contact point 14, and materially assist in power conservation.

It is believed, that applicants device as fully set forth herein, is distinguished from the references, for while applicants device does, incidentally, effect a maintained stability of the included mechanism, applicants device does further, and primarily, stabilize in power equilibrium, the internal stresses developed within the measures of applied power, as outlined herein.

The invention in its broader aspects is not limited to the precise constructions shown and described nor to the specific applications thereof.
